Abstract

Vitamin K deficiency, either dietary or pharmacologically induced by warfarin, was unable to affect the metastatic capacity of cells from a benzopyrene-induced fibrosarcoma in C57BL/6J mice. The same cells had a procoagulant activity, of tissue thromboplastin type, which was also completely unaffected by vitamin K antagonism or deficiency. In another murine model of spontaneous metastasis we previously suggested that depression of a particular procoagulant such as a direct factor X activator might contribute to the antimetastatic activity of warfarin. The failure of vitamin K deficiency to affect both the procoagulant and the metastatic capacity of the model reported here offers strong negative support to the same concept.
